Leaching performed at elevated temperature and pressure.

Note 1: A typical apparatus is shown in Figure.

Figure. Schematic diagram of a typical apparatus for pressurized liquid extraction. Gas flow is used to displace the extraction solvent from the sample chamber. Reproduced from ref. 39 with permission from Springer Nature, Copyright 2009.

Note 2: The sample, in the form of a fine powder or liquid supported on an inert solid, is packed into an extraction vessel and inserted in a closed flow-through system. The temperature, pressure, solvent type, and static and/or dynamic extraction time are varied to optimize the extraction performance.
